7df7b0 | 2014-10-03 | Per Hedbor | | Pike 8.1: Changes since Pike 8.0 (scratch area for future release notes)
|
2ac499 | 2011-03-09 | Martin Stjernholm | | ----------------------------------------------------------------------
|
dca676 | 2014-11-03 | Martin Nilsson | | New language features
---------------------
o Unlimited character constant size.
There is no longer any limit to the size of character constants,
e.g. 'acdefghijk' creates the bignum 0x61636465666768696a6b.
|
a72ec6 | 2016-01-04 | Per Hedbor | | o 'auto' type added.
This is much like a strict typed mixed. The actual type is deduced
compile-time.
|
8e1049 | 2016-01-31 | Henrik Grubbström (Grubba) | | Typical use is as the type for variables in foreach when looping over
complexly typed values, or as the type in macro-defined functions and
similar.
|
a72ec6 | 2016-01-04 | Per Hedbor | |
auto can be used as return type for a function, it will be the
logical or of all the types of the return statements in the
function.
o typeof(X) can now be used as a type.
The main use case is in macros, but it might be useful for other
things as well (as an example in a typedef).
typedef typeof(Val.true)|typeof(Val.false) bool;
typeof, when used like this, behaves very much like the C++
decltype() expression.
|
854a97 | 2016-06-03 | Per Hedbor | | o ** operator added. It's exponentiation and works with most
combination of numerical types (int,float,Gmp.mpq,Gmp.mpf,Gmp.mpz)
`** and ``** operator overloading functions added.
This introduces one incompatible change: Previously the "pow"
function called a "_pow" function in the first argument if it was an
object. It has now been changed to also use `** (or, rather, pow()
|
56daad | 2016-06-05 | Henrik Grubbström (Grubba) | | is now implemented using predef::`**()).
|
854a97 | 2016-06-03 | Per Hedbor | |
|
7a82ac | 2016-01-26 | Martin Nilsson | | o Random rewrite
The random functions have been rewritten to ensure security by
|
f8800b | 2016-01-26 | Henrik Grubbström (Grubba) | | default. random_string() and random() now get their data directly
from the operating system random generator, i.e. /dev/urandom on
most unixen. This is about half the speed compared with the
random_string function in Pike 8.0, but is now as secure as the
system random generator.
|
7a82ac | 2016-01-26 | Martin Nilsson | |
For consumers of random data that have additional requirements,
different random generators are exposed in the new module
|
f8800b | 2016-01-26 | Henrik Grubbström (Grubba) | | Random. The module has the following generators:
|
7a82ac | 2016-01-26 | Martin Nilsson | |
- Random.Interface
This is not actually a generator, but an interface class that is
inherited into all the other generators. It contains code that can
turn the output from the random_string method into random numbers
with different limits without introducing bias. It also contains
code for all the different variants of random() on different
types. This is currently not possible to implement in Pike code,
as the typing is too complicated and it is not possible to access
private/protected _random methods in objects.
- Random.System
This generator maps directly on top of the system random
generator. This is the default generator used for random() and
random_string().
- Random.Deterministic
|
f8800b | 2016-01-26 | Henrik Grubbström (Grubba) | | This generator creates the same sequence of random numbers for a
|
7a82ac | 2016-01-26 | Martin Nilsson | | given seed, with good pseudo random properties.
- Random.Hardware
|
f8800b | 2016-01-26 | Henrik Grubbström (Grubba) | | This generator accesses the hardware random generator, when
|
7a82ac | 2016-01-26 | Martin Nilsson | | available.
- Random.Fast
This generator takes entropy from the Random.System, but feeds
|
f8800b | 2016-01-26 | Henrik Grubbström (Grubba) | | it into a cryptographic pseudo random number generator to be
|
7a82ac | 2016-01-26 | Martin Nilsson | | able to output data fast. This is not the default random number
|
8aa0f5 | 2016-03-19 | Martin Nilsson | | generator to avoid loading crypto code on every startup.
|
7a82ac | 2016-01-26 | Martin Nilsson | |
|
f8800b | 2016-01-26 | Henrik Grubbström (Grubba) | | Comparing the different generators with each other gives the
following approximate speeds on a Linux system with hardware
random support:
|
7a82ac | 2016-01-26 | Martin Nilsson | |
Random.System 1.0
Pike 8.0 random_string 0.45
Random.Hardware 0.25
Random.Fast 0.20
Random.Deterministic 0.20
|
8aa0f5 | 2016-03-19 | Martin Nilsson | | Objects implementing the _random lfun now get two arguments, the
current random_string() and random() functions. This is convenient
for C-level functions that doesn't have to look up functions
themselves. Note that it is possible for a user to replace these
with non-conforming functions (returning values of the wrong type,
strings of the wrong length or shift size, and values outside the
given range) or even non-functions.
All code in Pike that uses random now uses the current random
functions (though in some cases fixed at object creation). This
allows for repeatable results if the random functions are replaced
with a deterministic random generator, such as
Random.Deterministic. Example:
Random.Deterministic rnd = Random.Deterministic( seed );
add_constant( "random_string", rnd->random_string );
add_constant( "random", rnd->random );
|
7a82ac | 2016-01-26 | Martin Nilsson | |
|
9654e0 | 2015-10-15 | Martin Nilsson | | Incompatible changes
--------------------
o Gz.crc32 now only returns positive results.
|
781fcd | 2016-05-13 | Per Hedbor | | o glob() has changed.
The main incompatibilities are that [ and \ are now special
characters in the pattern, and if you check the return value against
1 instead of checking if it's true, and use an array as the first
argument you will have to change your code.
This is in order to extend the glob function to cover what
'standard' glob functions do:
glob() now accepts quotes (\* to match a single *, as an example)
and handles ranges ([abc] for a, b or c, [a-z0-9] for a single
character between a and z or 0-9
You can also negate a range using ^ or ! ([^a-zA-Z] as an example).
When the first argument (the pattern) to glob is an array, glob now
returns which pattern in the array matched.

Use Sql.Result instead.
|
dca676 | 2014-11-03 | Martin Nilsson | | Removed features and modules

|
a72ec6 | 2016-01-04 | Per Hedbor | | o GTK1 library is deprecated, so glue code is removed.

|
9654f7 | 2016-04-12 | Henrik Grubbström (Grubba) | | o Concurrent.Future and Concurrent.Promise
These are used to simplify handling of asynchronous results.
|
951b44 | 2016-01-04 | Martin Nilsson | | o Crypto.Checksum
|
f5f00d | 2016-01-26 | Martin Nilsson | |
This module collect non-cryptographic checksums. Support for crc32,
adler32 and Castagnoli CRC (CRC32C).
|
951b44 | 2016-01-04 | Martin Nilsson | | o Protocols.HTTP2

|
35e4fd | 2016-02-01 | Henrik Grubbström (Grubba) | |
|
a72ec6 | 2016-01-04 | Per Hedbor | | New features
------------
|
be725d | 2016-01-04 | Martin Nilsson | | o Gmp.mpf is now implemented using gmpf if the library is available.
|
992e24 | 2015-08-24 | Martin Nilsson | |
|
35e4fd | 2016-02-01 | Henrik Grubbström (Grubba) | |
|
83a8f5 | 2015-11-09 | Martin Nilsson | | C-level API changes
-------------------
o The contract for functions is now changed so that a function is no
longer required to clean the stack. The topmost value of the stack
will be regarded as the return value and the rest of the items on
the stack, compared to before the function arguments were pushed,
will be popped and discarded. Efuns still have to clean their stack
as previously.
|
83a320 | 2016-01-29 | Martin Nilsson | | o Removed add_function, pike_add_function, pike_add_function2,
|
4903e8 | 2016-01-30 | Martin Nilsson | | simple_add_variable, map_variable and MAP_VARIABLE. This removes the
remaining few API:s where text types were used. Use ADD_FUNCTION and
|
f1dbf0 | 2016-01-29 | Martin Nilsson | | PIKE_MAP_VARIABLE instead.
|
83a320 | 2016-01-29 | Martin Nilsson | |
|
118000 | 2016-03-19 | Martin Nilsson | | o Removed the functions my_rand and my_srand. Use the random functions
|
8aa0f5 | 2016-03-19 | Martin Nilsson | | on the stack for _random lfuns, the push_random_string or look up
|
118000 | 2016-03-19 | Martin Nilsson | | the random function from get_builtin_constants(). For deterministic
pseudo random, create a private Random.Deterministic object.
|

dca676 | 2014-11-03 | Martin Nilsson | | Building and installing
-----------------------
o GMP 4.1 or later is now required.
|
9721ab | 2016-01-11 | Martin Nilsson | |
o C99 assumed
The configure tests will not check for functions defined in C99
anymore and C99 compiler support is assumed.
